Your builder/designer’s name (just in case you forget)

...and his/her contact information(in case you need to call about an issue with your home)

‘Fenestration’ is another word for openings in a building (i.e., windows and doors).

R-value vs. U-factorBoth of these numbers relate to resistance to thermal conduction, or insulation value.In a nutshell, higher R-values and lower U-factors equate to better insulation, which in turn leads to more comfort in your home and less wasted energy.

R = 1UHungry for a formula? Here you go:

BET BreakdownStruggling to make sense of the mysterious acronyms that dominate the Building Envelope Tightness section? Hopefully this will help a little.

ACH50

CFM50

(Air Changes per Hour at 50 pascals*)

(Cubic Feet per Minute at 50 pascals*)

*50 pascals is a simulated testing pressure

CFM50 is the measure of a flow rate—in this case, the volume of air that movesout of your house in a minute under simulated testing pressure.

ACH50 measures the number of times the air in your house changes out in an hour under simulated testing pressure.

3The Building Envelope Tightness (BET) section contains the results of the BET test conducted on your home. This test helps to determine how leaky the house is by depressur-izing or pressurizing a home with a device called a blower door.

Essentially a large, calibrated fan, the blower door helps to measure all of the leaks through the gaps and seams in a house. The energy code requires houses to achieve a value less than 7 ACH50 (see box to left for more on what this means).Why is a tight building envelope so important? A home without air sealing does a poor job of keeping conditioned air in and unconditioned air out. In the summer, this means hot and muggy air infiltrating and giving your HVAC equipment the workout of its life. Wintertime brings cold drafts and more energy wasted trying to keep a leaky house warm.

The primary components of your home’s exterior shell, or ‘building envelope,’ and their insulation values, known as R-values and U-factors (typical values* in red).

*The values listed may not necessarily coincide on the same compliancecertificate. For example, a house with a crawlspace likely will not have a basement, in which case basement insulation values would not be listed.

Load CalculationsInstalling high-efficiency mechanical equipment is important for energy savings, yet properly sizing this equipment through accurate load calulations is often just as significant. Some HVAC contractors habitually disregard this critical step, so be your own advocate and scrutinize this section.

Thinking about changing out your old HVAC equipment? Opting for a high-efficiency model (look for models with a high SEER or EER) could save you hundreds of dollars on energy costs.

Test those DuctsTesting ductwork for tightness is valuable not only for new homes, but also existing abodes. Finding a certified professional to test your existing home is as easy as visiting georgiapower.com/homeimprovements.

Duct testing involves the use of a duct blaster (a calibrated fan) and lots of tape. A certified tester will tape all of the supply and return grills in a home, pressurize the ductwork with the fan, and record and analyze the resulting flow of the fan.

Compliance Certificate LocationIf you live in a house built to the 2009 IECC (the current energy code), you should be able to make your way to your air handler (probably in your attic or basement) or electrical distribution panel to locate the compliance certificate.

Once you find it, check the values and visit southface.org/energy-codes for terms you don’t know. This certificate is the starting point for understanding energy efficiency in your home and empowering you as a homeowner.

// Check for mastic, a heavy-duty sealant, applied around the air handler and the joints and seams of ductwork. It’s required by the energy code and makes your ducts super tight.

Similar to the BET test, the Duct Tightness Test measures the air tightness of the ductwork that circulates conditioned air throughout your house. Leaky ducts can actually be one of the biggest energy drains in a house.

The Mechanical Summary outlines the types and efficiencies of your heating and cooling equipment. It also provides details on your home’s load calculations and who performed them.
